Want to crank up that home theater system? LG is hoping its new wireless speaker system will turn your entertainment area into your personal rockin' arena.

The LG Sound Bar and subwoofer works with LG's Smart TV platform to bring streaming content from Netflix, YouTube and Pandora from the Web to the living room via a Bluetooth connection with tablets, PCs and smartphones.

The Sound Bar is entering a market already stacked with similar wireless home speaker systems. Companies like Phillips, Sony and Samsung all offer similarly styled but cheaper speakers. But priced at $399.99 it costs less than the higher-end wireless speaker systems made by the likes of Harmon and Parrot.
